The Britax Roundabout 55 convertible car seat accommodates children rear facing from 5 to 40 pounds and forward facing from 20 to 55 pounds. The Roundabout 55 is purposefully designed and engineered to minimize the forward movement of your child's head during a frontal impact to reduce the risk of head injury with revolutionary Britax head safety technologies.

Base with SafeCell Technology features SafeCells designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat which normally propels the child toward the front seat
Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
Energy-Absorbing Versa-Tether features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat
Side Impact Protection comprised of deep side walls lined with energy-absorbing EPP foam distributes crash forces, shields from vehicle intrusion, and contains the head, neck and body
Tangle-Free, Five-Point Harness distributes crash forces across the strongest parts of the body and provides a secure fit
55-pound Weight Capacity for safety and comfort as your child grows
Rear and Forward Facing Recline for child comfort and positioning
High Density Comfort Foam provides an extra layer of padding to gently cushion your child
Two Buckle Positions for your growing child
Infant Positioning Insert may be necessary for small infants to achieve a snug fit of the harness around your child (sold separately)
